OK, so the non-legacy, non-LSI one is not the one to use -- although
it's the one I've been using all this time without apparent problems.
So which of the other two do I use? Legacy or LSI? (I'm using an LSI
FireWire card).

They have the same version numbers, but they are different drivers.
All this really tells you is that they are "in sync" with the version level of
Windows you are running.
You have to find the actual system file and look at that file's meta data to
figure out what is what.
Thanks, Bill.

I just finished discussing this situation with the Firewire developers
and here is their recommendation for setting the 1394 Windows driver
type when using the 3.5.5.10185 Firewire driver that was included with
PowerSDR v2.0.19 RC1.
"Our recommendation for 3.5.5 is to use the legacy 1394 bus driver on
Win7. This is primarily due to the extra CPU overhead that we
identified in Microsoft's new 1394 bus driver."
Please refer to this KB article for setting the Windows 1394 driver to
the legacy version
http://kc.flexradio.com/KnowledgebaseArticle50433.aspx
I see a choice of three 1394 drivers on my system:
a. 1394 OHCI Compliant Host Controller
b. 1394 OHCI Compliant Host Controller (legacy)
c. LSI1394 OHCI Compliant Host Controller
But whichever one I choose, Driver Details shows the same information:
"6.1.7600.16385 (win7_rtm 090713-1255)"
